RIM TOOL.

,.dpplieetion filed September 21, 1917. Serial No. 192,490.

been too compllcoted to be 'racticl9 and some of the more simple type eve not been successful in operotin .large size rims. It has been the purpose o this invention to cony.15 struct a. rim contrecting or breaking tool which shall be simple in design easy to operate, and safe in ell positions. 'fo insure that the rim tool will hold the rims in collapsed position, and that there will ce no danger of the rim springing into closed ,position while the driver is manipulating the tire, l I

have provided e lock orI latch which will positively hold the rim in its collepsed posiu tion. A reqnent objection to rizntools now on the market is that while the tool will move the ends of the rim, out of line in collapsing,

' but when it is desired to restore the rim to o true circle, the ends of the rim will strike and it is necessary to pry the overlapping ends with a screw' driver or other implement to cause the rim ends to passinto line. Itis one of the obiectsof this invention to so construct the rim tool that it is possible to expand the rim slightly, whereupon the rim ends will pass into line and there will be no interference et this point in restoring the 4 rim to a true circle:v l

These andother objects will appeer as the description ofthe invention proceeds, refer' au ence being had to the accompanying drewings, in which:

Fie, iis c longitudinal section through o, rim snowing theonenner in which the tool may be menipnletsd to expend the rim looking down on the rim 4coiled Wire having a-central straight `slightly thereby enabling the rim ends to vpal-ss intoV line.

The rim tooldevised' by me com )rises two U-shapedor .bifurcated levexs whic are pivoted to one another and are provided on the extremities with means to engage the ends of i the rim,.th`ere beingalso provided a device by which the tivo ends of the arms may be drawn together to clamp the rim." One of .the lll-shaped arms or levers is shown at 10 and at its extremities carries pins 11 which are adapted to enter holes in oneend of the' rim neer the split. The other U-shaped arm or lever is indicated at 12 and carries similar l -pins 13 adapted to enter. holes in the other end of the rim. The arm 12 is preferably shorter than the erm l0 and is located between the parallel side bars ofthe arm l0. A contracting bolt 14 is loosely mounted in the arms l0 and l2 and iserves as a-pivot' around which the levers may move. @ne end ofI the bolt is screw-threaded ond is provided with e Wing nut l5 by which vthe ends of the arms may be drown together siter the pins .l1 and i3 have been'pleced in their respective apertures, thus securely locking the tool in position. y

Loosely mounted on the central portion of the bolt 14 is n swinging catch or hook 16 which is preferably made of e Apiece of ece and two terminal coils, received oroun the contracting bolt 14,

The operation of the device is very simple and can be easily understood. lThe. wing 4nutl l5 being Withdrawn -on the end of the holt 14 the levers 10 end 12 are placed to enclose the rim ends and' the Wing not is tightened to drive the pins in the a ertures. The tool being in the position 's ovvn in Figure i, the operator grasps the longer lever l0 and moves it to thc right of the ligure and the rim is collapsedI or oontraeted to the position shown in Figure 3. The hook .i6 is now swunv around on the contractingr bolt until it taires over the end of the rim 4latch A. This serves tohold the rimy in. collapsed position and there is no. danger of it flyino1 back into position, which ieri into line on springing back as the end carrying the latch will interfere with the other end. By moving the lever 12 toward the right,as shown in Fi ure 4, it is possible to expand the rim sligtly enabling the two ends to pass into line It is obvious that various changes and modifications may be made in the form of tool shown here. It is possible to provide alternative constructions to accomplish the saine results, such, for-instance, as changing theform of lock for holding the rim in collapsed position or arranging it toenvage With a different portion of the rim. These and other changes may be made without departing frolnthe spirit of the invention. claim: 1.
